Filed: 1990-10-16
Abstract: Method, system and apparatus for metering fuel to an internal combustion engine via a carburetor (20) having a mixture conduit with a venturi (42) therein. A main fuel nozzle (70) supplies fuel to the venturi of the carburetor in response to the static pressure drop induced across an associated main fuel flow controlling restriction (36) by the engine intake induced air flow through the carburetor mixture conduit.
